I think that you should help with the kids (even when not asked). That's just the right thing to do. But, honestly, you didn't mean to touch her (you were unconscious) and now you've apologized. I wouldn't do it anymore. She needs to get over herself and stop making you wrong for accidentally touching her. I would stand up for yourself more-- even though I know it's terribly hard. (Been there myself :))You can still validate without being woosy, IMO (although it can be a fine line).
